He said: “We feel that the repercussions will be felt a bit further down the line when the word begins to spread.

“The PLP may find itself in a similar position of the previous government with an unsatisfied group of citizens knocking on their door.”

Mr Robinson said ITTP would back any non-violent bid for marriage equality.

He added: “The next step is for us to join in with other advocates and continue to try and make a change.

“We don’t want this to turn into a clash of conflicting mentalities but into a chance to gain mutual understanding.”

Civil rights group the Centre for Justice also said the change in the law was not a surprise — but it was still disappointed that Government “chose to roll back full marital equality”.

The comments came after MPs on Friday voted 24-10 in favour of the Bill to replace same-sex marriage with domestic partnerships.

But the Centre for Justice said it was “encouraged” by an amendment that gave recognition to all same-sex marriages celebrated outside of Bermuda.

The organisation also said it was encouraged by the “change of tone” in many speeches made by MPs during the debate in the House of Assembly.

The Centre for Justice added: “Several MPs acknowledged that this issue highlights a generational gap and philosophical difference between parents and their young adult children whose worldwide view in more inclusive and progressive.”

Justin Mathias, chairman of the Future Bermuda Alliance, the youth wing of the OBA, said the legislation was a “sad day” for Bermuda.

Mr Mathias added: “For us to be this close to being the first country to renege on same-sex marriage is baffling.”

He said: “There is a huge generational gap with many issues in our country, but on this single issue I believe it is at its greatest.

“The younger generations are far more progressive and believe that everyone within our community should have equal rights under the law.”

He added the majority of FBA members backed same-sex marriage.

Mr Mathias said: “The one thing we unanimously agree on is that it isn’t right to take away rights that have already been given to people within our community.

“We are in a new age and the world is changing.”
